This function imprints the given curves on the body by projecting them locally
down face normals.


Specific Errors:

    PK_ERROR_invalid_geometry   Invalid curve

    PK_ERROR_unsuitable_entity  The target body or supplied curves are
                                unsuitable for this operation

    PK_ERROR_cant_do_imprint    Failed to perform imprint



Edges and vertices are added to the body. These are the image of the curves on
the body under local projection down face normals. The edges created by this
imprinting are returned. These may include existing edges where the curves
project down onto existing edges.

The tolerance supplied is used to solve any resolution problems and may also be
used to create SP-curves on the imprinted edges.

The curves supplied must be finite - in particular unbounded lines are not
allowed, but trimmed lines are.

This operation doesn't work on a wire body or any body whose faces have no
attached geometry,
